To all 'whom it may concern:

Be it known that I, LEONARD RICHARDSON, of Brooklyn, Kings county, Stateof NewYork, haveinveuted a certain Improvement in Sheet- Metal Gans, ofwhich the following is a specication.

rDhis invention is applicable to a can made of tin or other sheet metal,to be used for holding hermetically sealed paints, varnish, or othersubstances, liquid or dry, in which the joint between the cover and thebody of the canis closed by a strip of thin metal; and the object of theinvention is to secure a more cheap, easy, and perfect closing of thecan by means of the strip than has hitherto been done in the ease ofstrip-cans, at the same time securing the easy removal of the stripwithout injury to the can or to lthe cover, or without renderingthecover uniit to be a secure, perfeet, and permanent cover to the canafter the strip has been removed.

Figure l is a vertical transverse section of a can-body. made accordingto my invention. Fig. 2 is a vertical transverse section oi' the cover.Fig. 3 is a vertical transverse section of a can embodying my invention,showing the can-body, the cover, and the strip in place. Fig. et is aside view of the can and a partial section, showing the relativepositions of the can-body, the cover, and the strip when the two lastare in their proper places. Fig. 5 is a side view of the can closed.

A is the cylindrical body of the can, made preferably of sheet-tin.Around the body, and at a proper distance from the top edge of the body,for strengthening the can against lateral pressure, is formed aperipherical rib, B. From the upper base of this rib the can-body slantsslightly upward and inward continuously to the edge, as denoted by a a.

The cover C is made with a iiange, c, projecting downward, when thecover is in position upon the can, about half the distance between thetop edge of the can-body and the peripherical rib. The lower edge of theliange is crimped or beveled inward, as shown at d, so as to receive andsupport the upper edge and a considerable part of the under surfaceofthe closing-strip F, as shown in the drawings at Fig. 3. When theflange orn the cover is thus beveled in, the cover grasps firmly andtenaciously the can-body, and the ridge c, at the upper side of thebevel thus formed, constitutes a serviceable guide to the soldering-ironwhen the strip is being soldered to the cover.

When the cover and stripF are in position the cover is supported by thetop edge of the cau-body, and also bythe slanting side ofthe can-body,which is grasped by the beveled crimped-in portion of the iange of thecover. The upper edge of the strip ts into the bevel d, anda portion ofthe under surface of the strip is soldered to the beveled portion of theflange of the cover, as indicated in the drawings, aud the lower edge ofthe strip is supported by the rib B at the point where itis adjacent tothe slant. When the strip is Asoldered to the can-body at this point theslant prevents the solder from running up and uniting the can-body andthe cover to each other. The closing-strip may have a free end, either'with or without a loop or ring attachment, or the end may be lightlysoldered down, as may be desired. ln manufacturing the can it will befound most convenient if the strip is tirst attached to the cover beforethe latter is put upon the can. This being done, and the cover thenbeing placed in position, the lower edge of the strip may be soldered tothe can, as described. In this part of the operation the rib B serves asa guide to the soldering-iron, in the same way that the ridge c of thelian ge of the cover serves as a guide for soldering the top edge of thestrip to the cover.' Ihe solder for attaching the strip to the coverandthe can-body should be sufficiently soft to part when a tangentialstrain is exerted longitudinally upon the strip.

The operation of hermetically closing the can having been alreadysuiiiciently described, it is obvious that in order to open it all thatis necessary is to grasp the free end of the strip, (having iirstdetached it, if it has been fastened down,) or the ring or the loop, ifit has been furnished with one, and by the exeroise of suficient forcetotear oft' the strip the solder will easily part, permitting this to bedone, and the cover will remain, to be taken off and replaced atpleasure, in the saine manner as an ordinary can.

I am aware that a sheet-metal can has been formed with aprojeeting beadnear its top,

IOO

and the mouth of the can contracted above said bead to receive a flangedcover, the strip to be torn oil' resting upon the bead and elnbracing astraight portion of the flange of the cover; butin my can, while theilange of the cover is bent inwardly to form an extended lip, the innersurface of which snugly gripes the inclined or beveled portion of thecan, the inclination of the outer surface of the ilange gives it a snugand griping it within the tearstrip, and the shoulder formed by thebending of the flange forms a guide for the solderingtool. A can-coverhas been formed with a shoulder to guide the soldering-tool in attachingthe strip; but in that case the flange is not inclined, and is formed ofa separate piece attached to the cover by soldering.

What I claim is- The can having the projecting rib B andinwardly-beveled portion above said rib, and 2o provided with the coverO, having the inwardlybent struck-up iange, forming the lip d andshoulder c, and the strip F, having its lower edge resting upon said riband its upper edge resting against the inclined outer surface of 25 saidange of the cover, substantially as and for the purpose set forth.

LEONARD RICHARDSON.
